Children of a secular god lack proper interest in others.
Ignoring the "secular god" oxymoron, secular people have an interest in FAR more people than fundies because we're not terrified that they're agents of Satan and don't masturbate to the thought of them going to hell. We can be friends with Christians, Muslims, Buddhists, Pagans, atheists, and anything else you've got and not throw a fit or try to convert them at every opportunity.

I thought secular people were promiscuous according to most fundies. Now we don't have enough sex? Hey, who cares about consistency as long as you're bashing the opposition, right?
Secular people don't dream? Then what the hell was I doing thinking about that nice car I eventually want to get?

Yes, all secular people are hermits. That's why you never see them in public. Oh wait.

They are typically users, needy and demanbding, used to getting their own way.
Are you talking about fundies here?
Living with one can be like sandpapering a bobcat’s behind in a phone booth.
And here too? Because that's the only way these two sentences make any sense as secular people are usually easier to live with than fundies as they're not constantly judging/evangelizing/fearing people who are different in any way.
